Fiber in Mango: How Much Is in a Cup or Whole Mango?

Mango has a moderate amount of fiber. According to USDA FoodData Central, raw mango provides 1.6 grams of fiber per 100 grams, about 2.6 grams in a one-cup serving of pieces (165 grams) and about 5.4 grams in a whole mango (336 grams of edible fruit). One cup covers roughly 9% of the 28-gram Daily Value, so mango is a useful contributor to your daily fiber rather than a high-fiber heavyweight.

Key Takeaways

One cup of mango pieces has about 2.6 g of fiber (9% of the Daily Value); a whole mango has about 5.4 g (19%).
Mango fiber includes both soluble and insoluble types; the flesh is described as a source mainly of soluble, pectin-type fiber, while the peel is richer in insoluble fiber.
Gram for gram, sweetened dried mango has more fiber (2.4 g per 100 g) but also about five times the calories and sugars, so fresh mango gives far more fiber per calorie.
Raspberries, pears and apples supply more fiber per serving than mango; mango works best as one of several fruits in a fiber-rich day.
A small 2018 pilot study found that eating mango daily improved stool frequency and consistency more than an equal amount of fiber alone.
Mango peel contains compounds related to the poison ivy allergen, so people sensitive to poison ivy or oak may react to handling it.

Evidence grade: Strong. Mango's fiber content comes from USDA laboratory food-composition data and the Daily Value is an established FDA reference value; research on mango's own digestive effects is limited to one small human pilot study.

How Much Fiber Is in a Mango?

Here are the numbers for raw mango from USDA FoodData Central:

Serving	Fiber	% Daily Value (28 g)	Calories
100 g raw mango	1.6 g	About 6%	60
1 cup mango pieces (165 g)	About 2.6 g	About 9%	About 99
1 whole mango, flesh only (336 g)	About 5.4 g	About 19%	About 202
100 g dried mango, sweetened	2.4 g (with about 66 g of sugars)	About 9%	319

Raw mango also has 13.7 grams of natural sugars and 36.4 mg of vitamin C per 100 grams, so a cup brings about 60 mg of vitamin C along with its fiber. The USDA values are based on analyses of common commercial cultivars such as Tommy Atkins, Keitt, Kent and Haden; individual fruits vary with variety and ripeness.

Is Mango High in Fiber?

Mango is a solid contributor rather than a fiber heavyweight. A cup gives you a useful amount, and eating a whole mango gets you close to a fifth of the Daily Value. For a fiber-rich day, pair it with other plant foods, such as oats in a smoothie bowl or black beans in a mango salsa. For more on mango's other nutrients, see why mangos are called a superfood.

Soluble and Insoluble Fiber in Mango

Dietary fiber comes in two main types. MedlinePlus explains that soluble fiber attracts water and turns into a gel during digestion, which slows digestion. Insoluble fiber does not dissolve in water; it adds bulk to the stool and appears to help food pass more quickly through the stomach and intestines. Both are part of a healthy diet.

Mango contains both. A 2014 review of mango nutrition describes the edible pulp as a source of soluble fiber, including pectin-type polysaccharides (rhamnogalacturonans), and the peel as richer in insoluble fiber such as lignin and hemicellulose. USDA FoodData Central does not report a soluble-to-insoluble split for mango, so treat any exact percentage you see online with caution.

Because most people eat only the flesh, the fiber you get from mango likely leans toward the soluble, gel-forming kind. That makes mango a different kind of fiber source from wheat bran or whole grains, which MedlinePlus lists among the insoluble-fiber foods.

Mango vs Other Fruits: Fiber Comparison

How does mango stack up? This table uses USDA FoodData Central values for raw fruit, with a typical household serving for each.

Fruit (raw)	Fiber per 100 g	Typical serving	Fiber per serving	Calories per 100 g
Raspberries	6.5 g	1 cup (123 g)	About 8.0 g	52
Pear	3.1 g	1 medium (178 g)	About 5.5 g	57
Kiwifruit, green	3.0 g	1 fruit (69 g)	About 2.1 g	61
Banana	2.6 g	1 medium (118 g)	About 3.1 g	89
Apple, with skin	2.4 g	1 medium (182 g)	About 4.4 g	52
Orange	2.4 g	1 fruit (131 g)	About 3.1 g	47
Blueberries	2.4 g	1 cup (148 g)	About 3.6 g	57
Strawberries	2.0 g	1 cup halves (152 g)	About 3.0 g	32
Papaya	1.7 g	1 cup pieces (145 g)	About 2.5 g	43
Mango	1.6 g	1 cup pieces (165 g)	About 2.6 g	60
Pineapple	1.4 g	1 cup chunks (165 g)	About 2.3 g	50

Mango sits near the middle of the pack, close to papaya and slightly ahead of pineapple, but behind berries, pears and apples. If you want the fruit with the most fiber, see our ranking of which fruit is highest in fiber.

How Mango Fits Your Daily Fiber Target

The Daily Value for dietary fiber on U.S. food labels is 28 grams. MedlinePlus puts the recommendation for older children, adolescents and adults at 21 to 38 grams a day, depending on age and sex, and notes that Americans eat about 16 grams a day on average. That leaves most people with room to add more.

A cup of mango closes about 2.6 grams of that gap, a whole mango about 5.4 grams. Combined with a serving of whole grains, beans or vegetables at other meals, mango helps make a higher-fiber day realistic. MedlinePlus advises adding fiber gradually over a few weeks and drinking enough fluids, because a sudden jump in fiber can cause gas, bloating and cramps.

Timing is up to you; some people prefer mango with breakfast or as a snack. Our article on the best time to eat mango looks at that question.

Does Dried Mango Have More Fiber?

Gram for gram, yes, because the water is removed. USDA lists sweetened dried mango at 2.4 grams of fiber per 100 grams, compared with 1.6 grams for raw mango. But the same 100 grams of sweetened dried mango has 319 calories and 66.3 grams of sugars, compared with 60 calories and 13.7 grams of sugars for fresh.

Per calorie, fresh mango gives you far more fiber: about 2.7 grams per 100 calories, compared with about 0.75 grams for sweetened dried mango. If fiber is your goal, fresh or frozen mango is the better everyday choice, and dried mango works best as a small portion.

What Research Says About Mango and Regularity

In a 2018 pilot study, otherwise healthy adults with long-term constipation ate 300 grams of mango a day (about 1¾ cups) for 4 weeks, while another group took an equal amount of fiber without the fruit. The mango group saw greater improvements in stool frequency, consistency and shape. The researchers suggested that mango's natural plant compounds (polyphenols) may work together with its fiber. It was a small study, and larger trials are needed, but it suggests that whole mango may support regularity beyond its fiber content alone.

MedlinePlus notes that soluble fiber slows digestion and that research links it to healthy cholesterol levels, but there is little research on mango itself for these outcomes. Mango's natural sugars mean portion size still matters; pairing it with a protein food such as yogurt makes a more balanced snack.

Add fresh or frozen mango cubes to oatmeal, yogurt or a smoothie.
Make a salsa with mango, black beans, red onion and lime for fish or chicken.
Toss mango into a salad with avocado and leafy greens.
Keep frozen mango on hand when fresh fruit is out of season; canned mango packed in juice works too.
Use dried mango sparingly, as a small add-in rather than a snack by the handful.

Mango Skin, Allergies and Safety

Most people eat only the flesh, and that is where the fiber figures above come from. Mango skin is technically edible, but there are good reasons to be cautious:

Mango peel contains resorcinol compounds that are chemically related to urushiol, the allergen in poison ivy and poison oak. Patch-test studies show cross-reactions between the two, and case reports describe skin reactions to mango in people previously sensitized to poison ivy or oak.
Mango food allergy can range from mild itching of the mouth to severe, life-threatening reactions (anaphylaxis).
A 2020 study of allergic children described clinical cross-reactivity among mango, pistachio and cashew.

For most people, the best approach is to wash and peel mangoes before eating them, and to wear gloves while peeling if mango skin or poison ivy has irritated you before. You still get a meaningful amount of fiber from the flesh alone.

Safety and Interactions

Add fiber gradually. Large, sudden increases in fiber can cause gas, bloating and abdominal cramps; increase over a few weeks and drink enough fluids.
Allergy: if you have had a reaction to mango, cashew or pistachio, or swelling or difficulty breathing after eating any food, talk to your doctor or an allergist before eating mango. Seek emergency care for trouble breathing.
Skin sensitivity: people with a history of poison ivy or poison oak reactions should peel mangoes with gloves and avoid eating the skin.
Sugars: fresh mango has about 13.7 g of natural sugars per 100 g and sweetened dried mango about 66 g. If you follow a carbohydrate plan from your healthcare provider, count mango portions accordingly.
Medications: if you take a medicine on a strict schedule or follow a prescribed diet, ask your doctor or pharmacist before making large changes to your fiber intake.

Frequently Asked Questions

How many grams of fiber are in one mango?

About 5.4 grams. USDA data put a whole raw mango at 336 grams of edible fruit, with 1.6 grams of fiber per 100 grams.

How much fiber is in a cup of mango?

About 2.6 grams in one cup of mango pieces (165 grams), or roughly 9% of the 28-gram Daily Value.

Is mango a good source of fiber?

Mango is a moderate source. A cup provides about 9% of the Daily Value and a whole mango about 19%, which is less than raspberries, pears or apples but similar to papaya.

What type of fiber is in mangoes?

Both soluble and insoluble fiber. The flesh is described as a source mainly of soluble, pectin-type fiber, while the peel is richer in insoluble fiber such as lignin and hemicellulose.

Does dried mango have more fiber than fresh mango?

Per 100 grams, yes: 2.4 grams for sweetened dried mango versus 1.6 grams for fresh. But dried mango has far more sugar and calories, so fresh mango gives you more fiber per calorie.

Should you eat mango skin for extra fiber?

It is usually best not to. Mango skin is edible but tough, and the peel contains compounds related to urushiol, the poison ivy allergen, which can irritate sensitive people. The flesh alone still provides a good amount of fiber.
